4.3.2 Port Mirroring
Configure port Mirroring on this page. This function provides the monitoring of network traffic that forwards a copy of each
incoming or outgoing packet from one port of a network Switch to another port where the packet can be studied. It enables the
manager to keep close track of switch performance and alter it if necessary.
 To debug network problems, selected traffic can be copied, or mirrored, to a mirror port where a frame analyzer can be
attached to analyze the frame flow.
 The PoE Web Smart Switch can unobtrusively mirror traffic from any port to a monitor port. You can then attach a
protocol analyzer to this port to perform traffic analysis and verify connection integrity.
Figure 4-3-2 Port Mirror Application
The traffic to be copied to the mirror port is selected as follows:
1. All frames received on a given port (also known as ingress or source mirroring).
2. All frames transmitted on a given port (also known as egress or destination mirroring).
